SALOMON HUMMEL, OF VIENNA, AUSTRIA-HUN GARY.

FRAME FOR EYEGLASSES.

SPECIFICATION forming part of Letters Patent No. 578,821, dated March16, 1897.

Application filed October 31, 1896. Serial No. 610,665. (No model.)

To all whom it may concern Be it known that I, SALOMON HUMMEL, a subjectof the Emperor of Austria-Hungary, residing at Vienna, in the Empire ofAustria- Hungary, have invented certain new and useful Improvements inFrames for Eyeglasses, Spectacles, and the Like, of which the followingis a specification.

My invention has relation to an eyeglassframe, and in such connection itrelates particularly to the construction and arrangement of such aframe.

'The principal objects of my invention are, first, to provide aneyeglass-frame adapted to be separated to release the glass or glassesand to be locked in closed position by means of a catch pivoted in oneof the separated ends of the frame and adapted to engage a pin orprojection in the other end,both catch and projection being concealed bythe body of the frame, and, second, to provide in an eyeglass-frameadapted to separate to release the glass a catch pivoted in one of theseparated ends of the frame, a projection in the other end thereof, anda pin and recess in the meeting ends of the frame adapted to guide thecatch into locking position with the projection.

Myinvention, stated in general terms, consists of an eyeglass-frameconstructed and arranged in substantially the manner hereinafterdescribed and claimed.

The nature and scope of my invention will be more fully understood fromthe follow-ing description, taken in connection with the accompanyingdrawings, forming part hereof, in which- Figure 1 is a front view of aneyeglassframe embodying main features of myinvention, the frame beingopen and partially broken away to illustrate the construction andarrangement of the catch therefor. Fig. 2 is a similar view illustratingthe closed and locked frame. Fig. 3 is a front view of a spectacle framewherein the frame is separable, the frame being illustrated in openposition; and Fig. 4 is a similar View of the spectacle-frame whenclosed.

Referring to the drawings, a glass A is secured in a frame a b, which,instead of being continuous or unbroken, is adapted to be separated oropened, as shown in Figs. 1 and 3. Both ends a and b are verticallyslotted, as at a, and in the, slotted portion of the end I) is pivotallysecured, as at f, a catch g, having at either end a projection g or 9 bymeans of which the catch 9 may be articulated in the slot of the end I).The catch g is also provided with a finger h. In the slotted end a isformed a ledge or projection 1', over or upon which the finger h of thecatch 9 is adapted to fit when the ends are brought together, as shownin Figs. 2-and 4, and to thereby lock the ends together.

In Figs. 1 and 2 the frame illustrated is that usually found in monoclesor pince-nez and usually carries the ring a for the chain or guard. Theframe and ring 0 may be formed in one piece, as shown, in which casethere is suflicient resiliency to the material of the frame and ring topermit the frame to open, as shown in Fig. 1. In Figs. 3 and 4 myinvention is illustrated as adapted for use in conjunction with theframe of spectacles. The frame a b may also, if desired, be providedwith a pin (1 on one end 1), adapted to enter a recess 6 in the otherend a and acting as a guide to bring the ends of the frame in alinement.

In operation the ends a and b of the frame are pressed together and thelower ing 9 of the catch f actuated to throw the finger h upon the ledgei. To release the ends of the frame, the upper lug g is shifted untilthe finger-piece 7t clears the ledge 2'.

By my present invention a glass or glasses may be quickly removed andreplaced by even the most unskilled, and the use of easily broken anddisarranged fastenings, such as screws, solder, and the like, isobviated.

Having thus described the nature and objects of my invention, what Iclaimas new, and desire to secure by Letters Patent, is-

The combination with the separable frame a, b, of an eyeglass, the endsof which are each vertically slotted, of the catch 9, pivotallyconnected with one end of said frame within the slot thereof, a ledge71, formed in the other slotted end of the frame, a finger In Witnesswhereof Ihereunto set myhand in presence of two Witnesses.

SALOMON HUMMEL.
